PROBLEM TO BE SOLVED: To provide an electrically-driven die cast machine excellent in workability capable of stably performing a series of molding cycles including an injection process, a boosting process, an ejection process, and a retreat process.SOLUTION: In an ejection process, a controller 13 controls the drive of an electric servomotor 10 for injection and/or an electric servomotor 11 for boosting according to a pre-set control pattern, and stops an injection plunger 9 at a predetermined ejection stop position. The controller 13 also controls the drive of each of the electric servomotors 10 and 11 so that, in a retreat process, the rotation speed of a screw shaft 5 by the electric servomotor 11 for boosting is higher than the rotation speed of the screw shaft 5 by the electric servomotor 10 for injection, and stops the injection plunger 9 at a predetermined initial position. |
